Don’t worry, just follow these simple steps.

To begin, log into your control panel and click on ‘manage email’ in the email section.

Using this drop down menu here, you will need to select the domain name that the mailbox belongs to.

Once you’ve selected the domain name, your mailboxes will appear just here.

Click on the ‘more’ button next to the mailbox you need to change the password for.

Now click ‘mailbox settings’ and under the preferences menu click on ‘edit.’

You can now enter your new password.

Remember when you are creating your new password to ensure it fits the password criteria.

It must be at least 8 characters long with a combination of upper and lowercase letters, as well as numbers.

It must also include at least one special character.

So once you’ve created your new password click ‘save’.

That’s it, your password has now been changed and you can use this new password to log into your 123-mail account using 123-reg webmail.

Please note that if you have set up your mailbox to send or receive emails in an email client such as Outlook, then you will also need to update this password to match your new one.
